'To ALL Sw-HQM" 1r MAY ooNoERN:

Be it 'known' theft I, ALPnoNsnJULIEN Lorsmu, of the city, county, and State of New York, have invented o. new aind'- improved .Stop-Motion for Looms; and I do hereby declare'that the following is a full, clear, and exact description lthereof, which -will enableothcrs skilled in the uut to make and us'e thesame, reference being,r had to the accompanying drawings, forming partof this speciiicattion, in-whiclr- 'j Figure 1 represents a. longitudinal vertical section of this invention -taken in the plone indicated by the .line iig. 2. v 'I Figure 2 is shorizontal section of the seme, the line yg indicating the' plane of section.

Similar letters of reference indicate like parts.

This inventionrclates to 'an uutom'atic lstop-motion which is brought into action whenever one ,of the warp threads breaks, eaeh warp threadbeing4 passend through an eye iu the -upper end of e.' short `:rochwliich hangs r4loy5 rn 'through a perforated plate in Asuch a position that it clears a.` crosssbar which is secured toia. pair of oscillating levers secured in the loom-frame, hut-if :one 'of the warp threads breaks, the s .ppropriaterod drops down and the oscil-lziting cross-bar forces the same against a rodlwhielh extends' across 'the loom-parnllel 'to the .perforatdplnt'e, Being vsecured to the upper end of leverswhiehrise fronte; rocksshaft, frein which extends an 'asin bearing a pusher whichV serves to. press ngazinstc springin' the front end of the loom, whenever one ofA the short rods drops downjas above/described. The lloose `endof ssidspring connects with a-dog which catches Q over-onehrm' of. an elbow-lever and' holds-the sme,-so thst`itsfoth`cr rzt'lru presses against Pue catch-bar and vprevents theseme from being caught by n, loop @hook-attached to thelay or htten.v If thespring is'acted on .by thepu'shc'r, the elbowdever is released, und thecatch-'bar drops so that the same is carried forward by the sc tionrof the lay, and the motioxio theiloo'm is s topped'either'hy shiftingv the belt or by a' directstop'.

Arepresents lthe vfrmneiof myloo'in, which is lmadefof wood ot any other material, and which forms the' bearings for the rocking-treeAB, 'to which the lay G's attached. c This lay is constructed inthe ordinary manner,

'and it my be made with one or n lore shuttles., andwith one Voinmore openings through which the wor'p'threadspass. O n their ourse fromt-he 'yarn-beam or spools, to the opening or openings in' the lay, the warp threirds lpass through eyes in the top endsA of 'short rdsfor weights a, which arc freely suspended from said warp threads andzpnss down throu-gh'holesV 'in a. perforutedplate, D. This plate extends'ncross the Iframe of the loom,4being fastened'to the saine in any suitable' manner; anditis`perforated withu'suii'icient number of holes to admit u rod orfweight `to' 'each warp thread. `If thejwofrp threads' ere stretchedatl their proper tension, the rods or weights a are raised izo-suche height that theyl will not copain-'contact with a cross-bur, E, towards which they urezpze'ssed by the action of spiate, F, which is fastened to luil;rating, armsGe These arms are suspended from pivots b .in the top of the loom, and theyreceive their 4motion by eccentric's c, on thedrlving-shaft H, or in any other-.suitable msnner. ,The ross-bar E' is secured to theptop ends of levers, I, which rise from a' rock-shaft, J, that hns'its bearings in the lower part of the'frame A, and from this rock-shaft 'extends an arm, K, to which is Lattaehed the pusher L. `T1iis1pusher terminates incluse prorriuiity to c dat spring, M, one end of which is .secured to theframeA, while its other loose end ccnnects by ulink, with u dog; e. If the spring M is in its `normalposition, saidfdog catches o'yer one anni,gan'ellrowfleuer,y, whichfhas its fulcrumon a pivot, yand 'theother arm, g, of which sustains the cntehbsr.N;. This bar passes' freely throu'ghaloop or'hook, z', securedto the under surface f the lay, :md it extends to the buck end of' the lo'oro, where t'tfonnects with an arm,

rising froma. roclishuft,v0,-which has its bearings in suitable' boxessecured tothe freine A4 To the arm j is' .alsopivoted the stop 7c, which rna'y lie mnde to uct ona stud, 7c', projecting from adisk',l l, onjthe driving-shaft', orl instead of this the arm j insybe connected to `the belt-shi'ppe'r--if the Vloom is driven by po'wcr. If one of the warp threads breaks so that the corresponding rod or 'weight afdropsdown, the plate F pushes saidrorl -ngziiust the cross-bnr and thereby the pusher lL is brought to bear on the spring M. As this springyields, fthe doge yis made to release the'elbow-leverfg, aud the cntchsbar N drops clowxys'o that-it is caught by the loop er hook.:I and carried forward. By this inotionof the catch-bar, the arm j is'tlirow'n forward and the stop k is" brought in such. aposit-ion that. it arrests the motiol'ix of the' driving-shaft. From thcrock-shaft O 'extends also an.- arm, m, which connects by a.' rod, n, with an arm, o, Iextending from u vertical rock-shaft, p, which has its' hearings in suitable brackets secured toA the frameA, near to its front. This vertical rock-shzift connects hy a lever, q, witha. slide, l?, secured to the breast orfront of th'e loom; and an arm; 1, extending from the rockshaftp, eonnects by@ pivot, s, fwith the dog e. By movingV the slide 'P in the directionfmafrked on it n'ig. 2, the elbow-lever g is A`brouht in such a position 'that it prevents the catch-bar Niro'mtengaging-*witli the loop or. hook z', but, by moving thelidein the dirion loppos'ite to smid nrrovv, the catch-bmis released land the loom is stopped. By this anrangementvthe automatic stop-,motion is: combined with the hand stop-motion and the Weaver is enabled to stop his loom'wheziev'er he pleases. I- um :Unire that automatic stop-:notions for loomshave been made `which operate when the weft thread'breaks; this I'ldo notA claimt."

What I claimas new, and desire to seoure by'Let'ters Patent, is-. The oscillating plateY F, and cross-bar- E, in eombination ,With'the Weights or ods a, dog e, @steh-bm- N, and stop 7c, constructed end operating substantially as and for the purpose Vdescribed'. Y
